Application July 13, 1934, Serial No. 736.,898 Claims. (011. 137 -93)This invention relates to floor valves and has for its object to providea new and improved device of this description. The invention has as afurther object to provide a floor valve for sup- 5 plying water tofixtures and which may be easily and quickly operated by the foot. Theinvention has as a further object to provide such a floor valve whichmay be easily and quickly adjusted without shutting off the supply. Theinvention has other objects which are more particularly pointed out inthe accompanying description.

Referring now to the drawing, Fig. l is a view of one form of floorvalve embodying the inven- 5 tion with parts broken away showing thetemporary cover thereon which is used during the building operations;

Fig. 2 is a sectional view through the valve illustrated in Fig. 1showing the floor cover removed and the push button in position;

Fig. 3 is a plan view of the temporary cover of Fig. 1.

Like numerals refer to like parts throughout the several figures.

Referring now to the drawing, I have illustrated a floor valve having acasing I which is located below the upper surface of the floor. Thiscasing has an inlet 2 and an outlet 3. The inlet 2 is connected with thewater supply and the outlet 3 is connected with the fixture inconnection with which the water is used, such for example as a urinal,closet bowl or any other suitable fixture.

Within the casing l is a main valve 4. This main valve is shown as apiston valve and has the seating member 5 which seats on the seat 6surrounding the opening I by means of which the inlet 2 is connectedwith the outlet 3. The main valve 4 is provided with a bypass passageway8,

the end 9 of which communicates with the chamber iii in connection withthe source of supply through the inlet 2.

In the portion 8 of the bypass, which is enlarged, is a bypasscontroller II. The bypass 8 connects the chamber III with the chamber l2above the main valve 4. The bypass controller normally rests on a seatl3 and is arranged with a groove l4 so that only a small amount of waterpasses therethrough when the bypass controller is seated, as shown inFig. 2.

Located above the main valve 4 is an auxiliary valve l5 which seats on aseat IS, the auxiliary valve controlling the opening I! which connectsthe chamber I2 with the chamber l8. This chamber 18 is connected withthe outlet 3 by the passageway l9. The auxiliary valve i5 is .connectedwith a member 28 which has a screw threaded portion 2! which engages aninternal thread 22 in the casing i. The member 20 has an annulus 23which engages an engaging member 5' 24, engaging a shoulder 25 on thecasing. The member 20 also has an annulus 26 which engages the packingmember 21, engaging a shoulder 28 on the casing.

The auxiliary valve I5 is provided with a stem 10 29 which passesthrough an opening in the member 20, there being a packing glandthroughwhich it passes, consisting of the threaded member 30 and thepacking member 3!. A spring 32 surrounds the valve stem 29 and engagesthe pack- 15 ing member 3! at one end and a stop 33 onthe valve stem atthe other end. The valve stem 29 is provided with means for engaging itwith a tool to turn it, and l. have shownthe groove 34 for the blade ofa screw driver. 20

Removably connected with the top of the casing l is a. floor member 35which has a downwardly projecting part 36 having a threaded connectionwith the casing I. Within the floor member 35 is a push button 31 whichis located with- 25 in a holding member 38. This push button is hollowand contains a valve stem engaging member 39 which is adjustably mountedin the push button and which engages the top of the valve stem. Thevalve stem engaging member l8 has a 3 stop 40 and the push button has acooperating stop member 4|. These members prevent the upward removal ofthe push button.

The valve stem 29- has a screw threaded opening at its lower end. andthere is a screw thread 35 ed stop member 42 therein which projectstherefrom. There is an engaging part 43 associated therewith whichengages some part on the main valve 4 when the main valve is lifted soas to limit the upward movement of this main valve. 40

Means are-provided for preventing the member 42 from rotating. As hereinshown there is connected to this member a piece 44 which has a pin 45sliding in an opening 46 in the member 20. When the device is installedthe casing HS 45 sunk into the floor before the floor is completed. anda cover plate 41 is placed over the top thereof, the cover plate havinga downwardly projecting screw threaded part 48 which engages internalscrew threads in the casing, as shown in Fig. 1. 50 This plate has agroove 49 for a tool so that it may be rotated into place and inposition, or remove it. The casing I of the valve is generally placed inposition before the floor is completed and the threaded part 48 of thecover plate 41 is of suillcient length so that the cover plate may beadjusted to bring its upper surface to the upper surface of the finishedfioor. After the floor is completed this cover plate is removed and theparts shown in Fig. 2 inserted in position. The downwardly projectingpart 36 of the floor member 35 is of sufficient length to permit theadjustment of the floor member to bring its upper face flush with theupper face of the floor. This adjustment is necessary because it is notpracticable to have the casing of the valve properly located withrelation to the upper surface of the floor. This adjustment, however,makes this wholly unnecessary, as the floor member can be adjusted tobring it to the proper position. The stem engaging member 39 of the pushbutton can then be properly adjusted with relation to the valve stem 29by moving it downwardly when it is necessary to move the floor member 35upwardly, and by moving it upwardly when it is necessary to move thefloor member downwardly. It will be seen that by means of thisconstruction the parts may be easily and quickly adjusted to bring theminto proper relation to the upper face of the floor and to the otherparts of the valve.

In the use of the device the floor member and push button are adjustedto the proper position and the party using it presses with his foot uponthe push button 31. This moves the auxiliary valve stem 29 and opens theauxiliary valve l5. Water then escapes from the chamber I2 up throughthe auxiliary valve into the chamber l8 and down through the passagewayl9. This reduces the pressurein the chamber l2 and the pressure in thechamber I0 lifts the main valve to open it and permit the water to passfrom the inlet 2 through the valve to the point of use. The user thenremoves his foot from the push button and the spring closes theauxiliary valve. The main valve rises until its movement is stopped bythe engaging face 43. Water then passes up through the bypass into thechamber I2, causing the main valve to be.seated. During the initialupward movement of the main valve 4 the bypass controller I I is movedupwardly. As the main valve approaches the upward limit of its strokethe part 43 engages the end of the bypass controller II and moves itdownwardly so that the water can easily pass up through the bypass intothe chamber H. The pressure in the chamber I2 and in chamber I0 is thensubstantially equalized and the bypass controller ll drops down on itsseat l3. The groove l4 then permits a small amount of water to passthrough the bypass and permits the main valve to slowly move down to itsseating position. The amount of water passing through the valve may beregulated without shutting off the water by simply removing the pushbutton and push button holding member and by means of a tool inserted inthe groove 34 of the valve stem, rotating such valve stem to vary theposition of the engaging face 43. The rotation of the valve stem causesthe member 42 to move up or down without altering the position of theauxiliary valve.

If it is desired to lessen the amount of water passing through thevalve, the engaging face 43 is moved toward the main valve, and if it isdesired to increase the amount it is moved away from the valve. Afterthe adjustment has been made the push button may be again inserted inposition.

A floor valve comprising a casing, a main valve thereindividing the casing into two chambers, a bypass connecting saidchambers, an auxiliary valve above the main valve, a stem therefor, astop device adjustably connected with said stem and adapted to be movedtoward or from said main valve to vary its upward movement, acontrolling member for the stem connected with the valve casing and inproximity to the floor level, and means for adjusting said stop devicewithout shutting off the water.
